chamber

A CLI tool that listens to audio input (microphone), saves the recording to a WAV file, and plays it back on the audio output (speakers).

That's it, that's all it does. I use it to record music from my audio sequencers (PO-33 and EP-133) and hear what is currently playing.

Features:

1. Works on Linux, even if you have PipeWire.
2. Dead simple.
3. You can force a specific audio input or output.
4. Saves in the best audio quality.
5. Single-binary distribution.
6. Blazing fast, with almost no sound delay.
7. Powered by crabs.

Installation

You'll need cargo, a Rust package manager.

cargo install chamber

Usage

Just run it:

chamber

It will start listening, and playing back the audio. By default, the WAV file will be saved into recording.wav in the current directory.

Run chamber --help to see available flags.
